Abstract

A through-air thermally bonded nonwoven fabric is provided. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value.

Claims (31)

1. A through-air bonded nonwoven fabric comprising:

the through-air bonded nonwoven fabric comprising a first surface, a second surface, and a visually discernible zone on at least one of the first surface and second surface, the visually discernible zone having a pattern of three-dimensional features, each of the three-dimensional features defining a microzone comprising a first region and a second region, the first and second regions having a difference in values for an intensive property, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms;

wherein the intensive property is basis weight;

wherein the difference in values for the basis weight for the first region and the second region is from about 1.2× to about 10× different; and

wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method.

2. The through-air bonded nonwoven fabric of claim 1 , wherein the first surface has a TS7 value of about 2 dB V 2 rms to about 12 dB V 2 rms, and wherein the second surface has a TS7 value different than the TS7 value of the first surface.

3. The through-air bonded nonwoven fabric of claim 1 , wherein the second surface has a TS7 value that is lower than the first surface TS7 value.

4. The through-air bonded nonwoven fabric of claim 1 , wherein the second surface has a TS7 value that is different than the first surface TS7 value.

5. The through-air bonded nonwoven fabric of claim 1 , wherein the second surface has a TS7 value of about 3 dB V 2 rms to about 8 dB V 2 rms, and wherein the first surface has a TS7 value different than the TS7 value of the second surface.

6. The through-air bonded nonwoven fabric of claim 1 , wherein the Contact Angle is between about 90 degrees and about 140 degrees, as measured by the Contact Angle Test Method.

7. The through-air bonded nonwoven fabric of claim 1 , wherein the Contact Angle is between about 110 degrees and about 135 degrees, as measured by the Contact Angle Test Method.

8. The through-air bonded nonwoven fabric of claim 1 , wherein the first region exhibits a Time to Wick of greater than 10 seconds, as measured by the Time to Wick Test Method.

9. The through-air bonded nonwoven fabric of claim 8 , wherein the Time to Wick is between about 10 seconds and about 60 seconds, as measured by the Time to Wick Test Method.

10. The through-air bonded nonwoven fabric of claim 1 , wherein the basis weight of every region is greater than zero.

11. An absorbent article comprising the through-air bonded nonwoven fabric of claim 1 .

12. The absorbent article of claim 11 , wherein the absorbent article comprises a topsheet, a backsheet, and an absorbent core positioned intermediate the topsheet and the backsheet.

13. The absorbent article of claim 12 , wherein the through-air bonded nonwoven fabric is the topsheet or is an outer cover material.

14. A package of absorbent articles, each absorbent article comprising the through-air bonded nonwoven fabric of claim 1 , wherein the package has an in-bag stack height of between about 70 mm and about 100 mm, according to the In-Bag Stack Height Test.

15. A through-air bonded nonwoven fabric comprising:

the through-air bonded nonwoven fabric comprising a first surface, a second surface, and a visually discernible zone on at least one of the first surface and second surface, the visually discernible zone having a pattern of three-dimensional features, each of the three-dimensional features defining a microzone comprising a first region and a second region, the rust and second regions having a difference in values for an intensive property, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value;

wherein the intensive property is basis weight;

wherein the difference in values for the basis weight for the first region and the second region is from about 1.2× to about 10× different, and wherein the basis weight of the first region and the second region are both greater than zero; and

wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method.

16. The through-air bonded nonwoven fabric of claim 15 , wherein the first surface has a TS7 value of about 2 dB V 2 rms to about 12 dB V 2 rms, and wherein the second surface has a TS7 value of about 3 dB V 2 rms to about 8 dB V 2 rms.

17. A through-air bonded nonwoven fabric comprising:

the through-air bonded nonwoven fabric comprising a first surface, a second surface, and a visually discernible zone on at least one of the first surface and second surface, the visually discernible zone having a pattern of three-dimensional features, each of the three-dimensional features defining a microzone comprising a first region and a second region, the first and second regions having a difference in values for an intensive property, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V 2 rms, and wherein the first surface has a TS7 value that is different than the second surface TS7 value;

wherein the intensive property is basis weight;

wherein the difference in values for the basis weight for the first region and the second region is from about 1.2× to about 10× different, and wherein the basis weight of the first region and the second region are both greater than zero; and

wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method.

18. An absorbent article comprising the through-air bonded nonwoven fabric of claim 17 .

19. A package of absorbent articles, each absorbent article comprising the through-air bonded nonwoven fabric of claim 17 , wherein the package has an in-bag stack height of between about 70 mm and about 100 mm, according to the In-Bag Stack Height Test.
